  2. What is “News” on the Internet? Continuously updated third-party content.

  3. Kinds of “Continuous” Updating • Real-time (seconds) • Near-time (minutes) • Some-time (hours)

  4. News Distribution Models • Syndication (black box) Drop-in content • Wire Service (white box) Content elements - some assembly required.

  5. Kinds of News Services • Wire Services – AP, UPI • Publication – Newspapers • Aggregation – COMTEX • Transcription – FDCH • Tabulation – stocks

  6. Current Standard for News • ANPA 1312/IPTC 7901 • Example:t7727fnsadu i krm-schedule advisory 10-01 0043^krm-schedule advisory

  7. NITF NML XMLNews NewsML PRISM IPTC 2000 XML Standards & Initiativesfor News

  8. Working Group: IPTC-2000 • International Press Telecommunications Council has a 30-year History • IPTC-2000 Initiative, with Multiple Working Groups, Launched Summer 1999 to Review News Interchange Formats • Members Include: The Associated Press, Dow, Reuters, UPI, NY Times, PR Newswire, Business Wire, etc.

  10. Organizations Involved in News Standards

  11. NITF-News Industry Text Format • Began in early 90s as an SGML replacement for ANPA 1312/IPTC 7901 • Roughly 8 years in the making • Converted to XML in 1998 • Ratified by the NAA and IPTC summer of 1999 • IPTC is currently considering “maintenance” proposals

  12. NML - News Markup Language • Genesis - Second Conference on New Grammars Sponsored by the New Media Center at the American Press Institute • “I have a barn! Let’s put on a show!” • Initiated by journalists, subsumed into NITF by the IPTC

  13. XMLNews • Created by WAVO Corp. and Megginson Technologies, Spring 1999 to support WAVO’s NewsPak Service • Two XML Documents per Story: XMLNews-Story = NITF XMLNews-Meta - RDF metadata • Open to Interested Parties - Supported, but not controlled by WAVO

  14. NewsML • Currently being defined • Chartered as a replacement for the IPTC Information Interchange Model (IIM) • May or may not produce an “alternative” to NITF • Aggressive (for IPTC) Schedule

  15. Relations Among Standards

  16. Relations Among Initiatives

  17. Content in Context • Custom Views (“personalization”) • Cross-referencing (“linking”) • Collection (“dossier”) - parallel display of multiple sources.

  18. Next Frontier: Analysis Services • Monitoring (alerts) • Abstracting/Summarizing (digests) • Synthesis - characterization, tabulation, extrapolation - (reports)

  19. Data, Information, or Knowledge • Data Service: Serving up information “as-is.” • Information Service: Profiling, filtering, cross-referencing… • Knowledge Services: Analysis, Synthesis, Editorial perspective

  20. WAVO’s Case • WAVO is in the business of “moving media.” • [We’re actually extraordinarily high-tech “paper-boys.”]

  21. WAVO’s Data Network Business

  22. Normalizing News • Syntax (form)Every story, regardless of provider, is delivered in the same format. • Semantics (meaning)Metadata codes mean the same thing, regardless of provider.

  23. NewsPak’s XML Documents • Goal: Use open industry standards. News Industry Text Format (NITF) • Reality: NITF had most, but not all the elements we needed. • Breakthrough: Use two XML documents instead of one! (XMLNews-Story and XMLNews-Meta)

  24. Normalization Transformations

  25. Normalization Pattern Spectrum
